LEWIS VAN D. SUTTON, 0F WEST NEWTON. PENNSYLVANIA- ROTARY-ENGINE.

SPECIFICATION forming part of Letters Patent No. 740,944, dated October 6, 1903.

Application filed February 24, 1903. Serial No. 144,565. (No modelo To all whom t may concern.'

Be itknown that I, LEWIS VAND. SUTTON, a citizen of the United States, residing at "West Newton, in the county of Westmoreland and State of Pennsylvania, have made certain new and useful Improvements in Rotary Engines, of which the following is a specification.

My invention is an improvement in rotary engines; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure lisa side elevation, and Fig. 2 an end elevation, of an engine embodying my invention. Fig. 3 is a vertical section on about line 3 3 ofrFig. 2. Fig. 4 is a partial section cn about line 4 4 of Fig. 2. Fig. 5 is a side elevation of the inner face ofthe inner.

elevation of the inner face of one of the inner cylinder-sections,showing the piston in a different position from thatshowninFig. Fig? is a detail plan viewon about the line 7 7 of Fig. G. Fig.8 is a detail perspective view of the abutment-head. Fig. 9 is a detail view, partly in section, showing connection between one of the pistons and the carrier. Fig. l0 is detail perspective View of the carrier. Fig. 11 is a detail perspective view of one of the pistons. Fig. l2 is a detail perspective' view of one of the feed-valves. of the inner face of the inner section of one of the cylinders, and Fig. 14 is a detail elevation of the inner face of the outer section of one of the cylinders.

In carrying out my invention I employ a suitable frame A, in which Yis supported in bearings the shaft B, which is the main shaft of the engine. This frame A also supports the cylinders C and D, which may be alike, except that they are rights and lefts and are supported in the frame so that they stand at an inclined angle to each other and at an in-` clined angle with respect to the shaft. In the construction shown the cylinders are arranged close together at their lower ends and diverge toward their upper ends, so that they afford space between them for the operation of the carrier, presently described. The shaft is provided with cam-grooves E for operating 5o the rocking feed-valves and with eccentrics F for operating the abutment-heads, as will Fig. 13 is detail elevationbe more fully described hereinafter. The cylinders are shown as annular tubes consisting of two sections-an inner section C or D and an outer section O2 or DZ--the sections being fitted together at their inner faces and bolted or otherwise secured, sovas to present a circular cylinder for the operation of the steam and of the piston, as desired. Each cylinder is provided with a casing G for the feed-valve G and with a port g', leading from such valve into the casing at one side of the abutment H, as best shown in Fig. 14 of the drawings.

As the construction of the feedvalves and of the abutments and of the devices for oporating the same are alike in connection with both cylinders, except that they are operated with certain relation to each other, the description of one will answer for both.

The abutment H operates in suitable guides Within a casing H' and has a rod H2, provided with a pistou H3, operatim.r in a cylinder H4, v

having a steam-chest H5, provided with a slide-valve H6 of suitable construction for controlling the admission of steam to the opposite ends of the cylinder H4 and the proper exhaust of such steam in the operation of the engine. The steam is supplied to the chest H5 through a pipe H7, and the valve H6 is operated by a rod'H8 from an eccentric F8 on the shaft B. Bythis construction, the eccentric being lproperly set, steam will be admitted to move the abutment across'its cylinder after the piston,.presently described, has passed the abutment, so that steam supplied by the feed-valve will loperate between said abutmentH and the rear end of the piston to drive the same forward, as desired.

The feed-.valve G is shown as a rocking valve rocking within a casing G', to which steam is supplied by a pipe G2, and having a port g, whichinay be turned into and out of register with the feed-port g', leading to its cylinder. This valve G yhas a shaft G3, provided with a crank-arm G4, having a pin G5 entering the cam-groove F. on the shaft B. It should kbe understood that the cam-grooves should vbearranged as shown, so that the valves will operate alternately-@that is to say, one valve will be feeding steam to its cyiinderwhen the other valve is cut out.

IOG

This may be effected by the arrangement of the cam-grooves as shown in Fig. 3 of the drawings.

In the inner sections of the cylinders I provide slots I, through which project webs or anges on the carrier, presently described. The purpose of this carrier is to receive motion from the pistons as the latter are driven by the action of the steam and to carry the pistons after the steam has exhausted around to the point where they can receive the steam, and by arranging the same to act alternately in the two cylinders I am able to secure a practically continuous operation of the shaft through the carrier, as will be understood from the following description. The pistons J are in the form of long curved cylindrical bodies which are packed at J near their rear ends and are provided near their opposite or forward ends with openings or recesses J2 for engagement by the lugs or projections K on the carrier K. This carrier K is secured upon the shaft B and is arranged and operates between the opposite cylinders C and D and is provided on its opposite sides with the projecting webs or [langes K2, which extend circumferentially around the circular carrier K fora portion of its circumference and project laterally from the body 7c of said carrier, so they may enter the slots I and operate within the cylinders C and D throughout a portion of the length of the said cylinders, the slots I extending only for a portion of the length of the cylinders and the arrangement of the cylinders in a plane at an angle to that of the carrier permitting such operation, as will be understood from the drawings. The webs K2 are arranged at one end, k2, to operate in rear of the pistons J in order to force said pistons around toward the position where they will be operated upon by the steam admitted from the feed-valve, the lugs or projections K' being arranged at the opposite ends of the webs K2, so they may enter the recess J2 in the front ends of the pistons J, so the pistons J will operate the carrier while the said piston is being positively operated by the admitted steam. It will thus be noticed that when the steam is admitted to operate upon the pistous J, the parts being in the position shown in Fig. 1, the lugs K on the carrier will be engaged in the recess J2 of the piston, so the said piston Will positively operate the carrier until the steam-pressure is relieved from the piston J, after which the end of the web K2 opposite the lug K will engage in rear of the piston J' and will operate such piston around toward the point where it takes steam, the abutment-head being properly operated by means of the eccentric, as before described.

From the foregoing description, in connection with the accompanying drawings, it will be noticed that when the piston is in position shown in Fig. 5 steam will be in the space between said piston and the abutment-head H and will operate the piston in the direction indicated by the arrow in Fig. o until such steam exhausts. As the piston is operated by the pressure of the steam it carries with it the intermediate carrier by the engagement between the front end f said piston and the carrier, effected in the construction shown by means of the lug K entering the recess J, as will be understood from Figs. 9, 10, and l1. After the piston has passed the point where it is operated upon by the steam the rear end 7c of the blade K2 will adjust in rear of the piston and will operate to carry'the piston around toward its position to takesteam,`the carrier being operated during thislatter movement by its positive connection with the piston of the other cylinder, as will be understood from Fig. 3 of the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
